As the invention of cars become common around the world, most cities became full of autos. This resulted in a lot of traffic jam which requires a lot of traffic police to organize the movement of these cars. In the past traffic police have to work day and night at traffic crossing. However, J P Knight who worked at that time as an engineer for railways signalling thought about finding a good solution for this problem. Therefore, he invented these
Traffic signals in order to make roads safer and to reduce the number of traffic police on roads.

Advantages of Traffic Signals

There are a lot of advantages of obeying traffic signal: firstly, it helps in controlling speed. This is important because of the fact that speed often results in a lot of traffic accidents. For instance, if there are not traffic signal, reckless drivers will not slow down when there are some pedestrians crossing the road. In addition, traffic lights efficiently organize cars movement in crossing to avoid committing accidents.

Disadvantages of Traffic Signals

There is only one overt disadvantage of traffic signals. The allocated time for each line is controlled by the traffic lights. This means when the light is red, drivers have to stop even if there is no any car in the other lines. However, this is excessive delay can be controlled. There should be a traffic police in charge of each traffic light to change the sign swiftly accordingly. All in all, traffic lights are essential when it comes to road safety.

Do you feel bored of driving everyday commuting from home to work and so on? Do you consume most of your time driving in peak traffic jam and much of your work remains undone? Do you suffer from committing accidents from time to time? Then autonomous cars are here for you to get rid of all these problems. These driverless vehicles or in other words self-driving cars already starting to hit the roads of cities across UAE.
First of all, since many people have to do the daily routine of commuting from home to work, taking children to school every day…etc; they can live headache-free by assigning these routines to self-driving vehicles. The time, effort and concentration which are spent on roads can be saved and used efficiently instead on something beneficial, for instance, reading a book, completing backlogs, preparing tasks, etc. Not only this, but in term of safety on roads these modern vehicles are safer, since they are supported by a lot of sensors and cameras which both calculate the speed and the distance in a very accurate manner.
Secondly, you do not need to press the clutch, change the gear, press the accelerator meanwhile leaving the clutch gradually and doing the same in every gear change; this is a waste of physical effort and concentration. The well-designed system of these cars will do all these actions smoothly and harmoniously. What all you need is just to adjust the map to the place where you want to reach.
Finally, before starting the journey, the car often filters all roads to choose the ones that are not occupied. It is true that even in the case of manual driving the same can be done, but there is a risk of committing an accident, since the driver has to look at the map from time to time.
In conclusion, driverless vehicles can improve our life in many potential ways; being more environmentally friendly, time saving and safer to drivers and pedestrians alike. After all these, I do not think that you will be hesitant to try an autonomous vehicle.

The stability of oil price is essential because of the fact that it affects the economy of the world, as well as the U.S. In some countries, the price of commodities varies with accordance to the price of petrol and this is due to transportation costs. A recent estimate of petrol price around the world is approximately 1.10 U. S Dollar per liter according Global Petrol Prices. However, there are mainly two factors that affect oil price negatively or positively: oil production and taxes.

Firstly, countries which are ranked as top oil-producers are characterized by cheaper prices definitely, such as: The United States, Saudi Arabia, Russia, Canada, China, Iran, Iraq, United Arab Emirates. The more the country’s domestic gasoline production booms, the lower the price gets. What is surprising is that although Venezuela is not ranked as one of the top oil productive countries as previously stated, petrol is cheaper than water.
Secondly, in most countries, taxes are highly imposed on fuels which is not only used in transportation as mentioned so far, but it is used most importantly to power agricultural vehicles and machines. This in turn affects the commodities viciously. On the other hand, some environmentalists have a second thought, they believe that petrol should be taxed even higher, and this means there will be more efficient use of oil in order to minimize the danger of pollution that our environment and health is facing. Another vital and interesting point is that this high imposed taxation on fuel encourages carmakers to develop and sell low-carbon technologies. Moreover, it stimulates the share of public transport, walking, cycling and encouraging the use of electric-cars.
All in all, in order to avoid this futuristic dilemma, it sounds reasonable to design state-of-the-art electric autos, even if it is so costive. These will probably be the targeted kind of cars in U.A.E and around the world.

Do not be surprised if you find yourself able to move in a top gear drive in the southern part of Dubai as the project that has been launched in 2013 is about to be accomplished. It is the most essential project ever present in the history of the region. It is a 438-hectare area dedicated to 2020 events. Most importantly, this Metro Line will connect participants, innovators, policymakers, tourists, etc. around the world. It is a five-stage project which will extend the established Dubai Metro Red Line to the Expo 2020 site. Furthermore, the project will serve various existing mixed-use high-density corridors in southern Dubai.

Most national and international engineers were mesmerised taking part in the Route 2020 project establishment. People form different parts of the world flood to Dubai for different purposes and this is why it is well known by being a cosmopolitan city. For this reason, the peak traffic jam is not a novice idea to any one visiting this attractive place. As a result, the Dubai Roads and Transport Authority (RTA) exerted as much effort as possible to overcome this problem. The main essential components of the project will serve several existing mixed-use high-density corridors in Dubai South, in addition to newly planned transit-oriented developments along the line. It includes the following components:

First: A 15-km-long alignment consisting of 11.8 km of elevated guideways and 3.2 km of tunnel

Second: Seven LEED (Leadership in Energy and Environmental Design) Gold stations consisting of one interchange station, three elevated stations, two underground stations, and the special-event Expo Iconic Station

Third: Fifty additional trainsets (15 for the Route 2020 project and 35 to further improve service and expand capacity on the existing Red Line)

Fourth: Expansion of the Jebel Ali Depot accommodating the new rolling stock

Fifth: Construction of three new main power supply (MPS) stations and one additional traction power supply station (TPS)

When you arrive at Dubai International Airport the new line will provide you a single-seat journey to Expo 2020 site. What is promising is that the new Rout will probably extends to the Al Maktoum International Airport and provide direct connectivity by your vehicle between both international aviation hubs of Dubai.

One of GMC’s most popular cars, the Yukon, has been confirmed to be heading to the Middle Eastern market in a variety of 2019 model specifications. This includes the Yukon, as well as the Yukon XL, Denali, and the Denali XL.

Dubai buyers looking for a large, comfortable SUV that boasts power folding seats in both the second and third rows will find a lot to love about the new Yukon.

The front of the 2019 Yukon provides quite the bold statement, with projector-beam headlights offering much improved visibility – along with safer driving both at night and in bad weather. The option of a hands-free tailgate is also available, to make loading the Yukon with heavy shopping that much easier.

More of the 2019 Yukon’s features

Smokey Quartz, Dark Sky, and Pepperdust are the three colours that will be available for the 2019 Yukon, all of which are metallic for added visual appeal.

The Yukon is considered one of GMC’s flagship SUVs, and so it benefits from a luxurious interior. Comfortable leather combines with an 8-inch full colour touchscreen, complete with Apple CarPlay and a premium BOSE sound system.

It also features other touches to make living with the large SUV that little bit easier, such as a crisp reversing camera and remote-start functionality.

Enhanced Driver Alert and Lane Keep Assist packages are available as extra options. Side blind-zone, forward collision and rear cross alerts, automatic front braking, and adaptive cruise-control are all standard.

Under the Yukon’s hood

The Yukon is a heavy vehicle, large in size and loaded with luxury and safety features, so it needs a powerful and capable engine.

That comes in the form of the 5.2 litre EcoTec3 V8 for the Yukon SLE and SLT models. The Yukon Denali and Denali XL will feature the tried and true 6.2 litre V8 – offering a very healthy 420 horsepower and 624 Nm torque. This makes the Yukon an excellent choice for those who need to regularly tow trailers.

Price-wise, the Yukon is expected to start in the region of AED 179,999, with the cost increasing for higher-specification models in the range.
